Hi,
on which device are you doing NAT? post output from:
-sh ip int br | exc una
- sh ip route

I'm doing the config on the 2801 Router, my svi LAN is 192.168.20.0

Hi,
can you modify your default route and configure it with next-hop instead of outgoing interface.
Regards.

I have changed my default route to 0.0.0.0 0.0.0.0 to fastethernet 0/0 if that was what you were reffering too, i also changed the default router on SVI to 10.1.1.1 .
10.1.1.1 is the Fa0/1 interfafce on 2801
But still no luck, is my NAT configuration correct ? maybe I can configure again from scratch. ???

I'm sorry F0/0 is the 10.1.1.1 on 2801 router, and 10.1.1.2 is Fa0/9 switchport interface on 3550.

Hi,
you had something like this: ip route 0.0.0.0 0.0.0.0 f0/1 and you should change to something like this:
ip route 0.0.0.0 0.0.0.0 67.85.x.x which is the ISP default gateway they gave you.
Regards.
